Chapter 41 : Antitubercular Drugs Questions
Question 1 of 5
The nurse will assess the patient for which potential contraindication to antitubercular therapy?
Correct Answer: D
Rationale: Results of liver function studies (e.g., bilirubin level, liver enzyme levels) need to be assessed because isoniazid and rifampin may cause hepatic impairment; severe liver dysfunction is a contraindication to these drugs. The other options are incorrect.
Question 2 of 5
When monitoring patients on antitubercular drug therapy, the nurse knows that which drug may cause a decrease in visual acuity?
Correct Answer: C
Rationale: Ethambutol may cause a decrease in visual acuity or even blindness resulting from retrobulbar neuritis. The other options are incorrect.
Question 3 of 5
A patient has been taking antitubercular therapy for 3 months. The nurse will assess for what findings that indicate a therapeutic response to the drug therapy?
Correct Answer: D
Rationale: A therapeutic response to antitubercular therapy is manifested by a decrease in the symptoms of tuberculosis, such as cough and fever, and by weight gain. The results of laboratory studies (culture and sensitivity tests) and the chest radiographic findings will be used to confirm the clinical findings of resolution of the infection.
Question 4 of 5
The nurse is counseling a woman who will be starting rifampin as part of antitubercular therapy. The patient is currently taking oral contraceptives. Which statement is true regarding rifampin therapy for this patient?
Correct Answer: C
Rationale: Women taking oral contraceptives and rifampin need to be counselled about other forms of birth control because of the impaired effectiveness of the oral contraceptives during concurrent use of rifampin.
Question 5 of 5
The nurse is reviewing the medication administration record of a patient who is taking isoniazid. Which drug or drug class has a significant drug interaction with isoniazid?
Correct Answer: C
Rationale: Taking INH with phenytoin will cause decreased metabolism of the phenytoin, leading to increased drug effects. Pyridoxine is often given with isoniazid to prevent peripheral neuropathy. The other options are incorrect.
